The Gadget: Velform Smile system, 33 from www.jml direct.com and JML Direct TV.

What's it good for? This system offers dental surgery techniques in the comfort of your home.

How it works: Paint on the whitening gel, insert the mouth piece and shine the light on your teeth to activate the treatment, which removes surface stains and penetrates to get to work on deeper discolouration.

Beauty cheat: Macleans White & Shine Toothpaste, 2.59, has a dual-action formula with particles to gently polish away imperfections on the surface of your teeth, giving you a light reflective sparkle.
